DAC8 went live on January 1, 2026. If you hold crypto in the EU, your exchange is now automatically reporting your trades to tax authorities. Italy raised its rate to 33%. CARF is rolling out across 40+ countries.
I built 4 free tools to help crypto investors navigate this new landscape. No signup, no data collection — everything runs in your browser.
1. Crypto Tax Calculator by Country (40+ Countries)
The #1 question every crypto investor asks: "How much tax do I owe?"
This tool covers 42 countries with 2026 rates:
- Select your country, enter your gains, pick short-term or long-term
- See your estimated tax, effective rate, and net after tax
- DAC8 and CARF badges show which reporting frameworks apply to you
- Tax-free countries highlighted (UAE, Singapore, Switzerland, Hong Kong)
Key data points that surprised me building this:
- Japan taxes crypto at up to 55% (highest in the world)
- Germany is 0% if you hold over 1 year
- Italy jumped from 26% to 33% in January 2026
- Indonesia charges only 0.1% per transaction

2. Crypto Portfolio Rebalancer
Most paid rebalancers (Shrimpy, 3Commas) charge $19+/month. This one is free.
Enter your coins with current values and target allocation percentages. The tool calculates exactly what to buy and sell:
- Dynamic rows — add up to 10 coins
- Shows portfolio drift percentage
- BUY/SELL/HOLD actions with exact dollar amounts
- Total trades summary
No API calls, no exchange connection, no wallet linking. Just math.

3. Fear & Greed DCA Backtester
"Be fearful when others are greedy, and greedy when others are fearful" — but does it actually work for DCA?
This tool backtests two strategies against real historical data (2018-2025):
- Regular DCA: Buy every month regardless of market sentiment
- Fear DCA: Only buy when the Fear & Greed Index is below your threshold
Set your monthly amount, threshold (default 25 = Extreme Fear), and date range. See side-by-side comparison of total invested, BTC accumulated, ROI, and average buy price.
Spoiler: the results depend heavily on the time period. Fear DCA crushes regular DCA in periods that include crashes (2018, 2022). Regular DCA wins during sustained bull runs.

4. EU DAC8 Tax Estimator
